Hydrolysed Liver Powder is a soluble ingredient, we rate this product very highly indeed. Liver powders have been used in the production of high-quality feeds for years. With its high solubility, this powder is one of the best attractors both olfactory and gustatory out there for all aquatic species. it is a light brown colour. It contains vitamins B12, Folic Acid, and Iron. It can be used all year round to enhance any bait but works exceptionally well in colder months. An awesome fish attractor. Liver powder can be used up to 50g/kg
